Compact AM4 platform
The ASRock Fatal1ty B450 GAMING-ITX/AC is a Mini-ITX motherboard for AMD Ryzen 2000 and 3000 series processors. It targets builders who need a small-form-factor system with integrated Wi-Fi and dual-channel DDR4 support. The board uses the AMD Promontory B450 chipset and fits cases designed for the ITX footprint.
Straightforward ITX build
Installation follows the standard Mini-ITX pattern with two 288-pin DDR4 slots and a single PCIe 3.0 x16 slot. The vertical M.2 Key E socket ships with the 802.11ac module already fitted, so wireless is active immediately. A common issue is forgetting to update the BIOS before installing a newer Ryzen 3000 CPU, which prevents the system from posting.
B450 interface limits
The chipset provides four SATA 6.0Gb/s ports with RAID 0, 1 and 10 support. The Ultra M.2 socket runs at PCIe 3.0 x4 (32Gb/s) with Matisse, Summit Ridge, Pinnacle Ridge, Raven Ridge or Picasso CPUs, but drops to x2 (16Gb/s) with other supported processors. Memory tops out at 32GB across two slots, and the LAN controller is limited to 1Gbps.
Rear I/O includes HDMI
The rear panel carries an HDMI port driven by the APU’s integrated Radeon graphics, supporting DirectX 12 and up to 16GB of shared system memory. Audio runs through a Realtek ALC1220 codec delivering 7.1 channels. No legacy video outputs are present, so a discrete GPU or compatible APU is required for display.

Frågor om den här produkten
Will my existing DDR4-3200 modules run at their rated speed with a Ryzen 3000 processor?
Yes. The board supports DDR4 3200, 2933, 2667, 2400 and 2133 with Matisse CPUs, so 3200 is a native JEDEC speed for that generation.
Can I add a fast M.2 SSD and still use the supplied Wi-Fi module?
Yes. The Ultra M.2 socket (Key M, 2280) handles PCIe Gen3 x4 or SATA drives, while Wi-Fi uses a separate vertical Key E socket on the rear I/O.
Is the onboard 1 GbE LAN port sufficient for gigabit internet plans?
The Intel i211AT controller provides a dedicated PCIe 1 Gbps link, matching typical gigabit fibre or cable subscriptions.
